Methods of and apparatus for drilling, casing and/or completing a borehole (50) wherein one or more portions (50a to 50e) of the borehole (50) are drilled into a formation (52) at a single diameter along the entire length or depth of the or each portion (50a to 50e) of the borehole (50). An expandable tubular member (54a to 54e) is then located within the or each portion (50a to 50e) of the borehole (50) and radially expanded in the or each portion (50a to 50e) to line and/or case it or them. Optionally, a corrosion resistant member (56) and/or a service string (62) can be located in the borehole (50). An advantage of certain embodiments is that a single diameter borehole (50) is formed along the entire length or depth thereof.

Cette invention concerne des procédés et un appareil servant à forer, à cuveler et/ou à achever un trou de forage (50), une ou plusieurs parties (50a à 50e) de ce trou de forage (50) étant forées dans une formation (52) d'un seul diamètre le long de la totalité de la longueur ou de la profondeur de la ou des parties (50a à 50e) du trou de forage (50). Un élément tubulaire extensible (54a à 54e) est ensuite disposé à l'intérieur de la ou des parties (50a à 50e) du trou de forage (50), puis il est étendu radialement dans chaque partie (50a à 50e) afin de procéder à l'alignement et/ou au cuvelage de chaque partie. Dans une autre variante, un élément anticorrosif (56) et/ou un train de tiges de service (62) peut être disposé dans le trou de forage (50). L'avantage de certains modes de réalisation de cette invention réside en ce qu'un trou de forage (50) à diamètre unique est formé le long de toute la longueur ou de la profondeur dudit trou de forage.
